To find the probability that a randomly selected bottle is correctly placed AND is a Plastic #4 bottle, we need to look at the number of Plastic #4 bottles that are correctly placed and divide it by the total number of bottles.
Correctly Placed Plastic #4 bottles = 5
Total Plastic #4 bottles = 5 + 2 = 7 (correctly placed + incorrectly placed)
Probability = Correctly Placed Plastic #4 bottles / Total Plastic #4 bottles
Probability = 5 / 7 = 5/7
Therefore, the probability that a randomly selected bottle is correctly placed AND is a Plastic #4 bottle is 5/7.
The correct answer is 5 over 7.

What is the probability that a randomly selected bottle is correctly placed AND is a
Plastic #4 bottle?
